Cobra

Cobra is a all-natural male enhancement supplement containing muira puama, better known as Brazilian "potency wood", which improves sexual performance. Other ingredients, such as ginseng, also supposedly improve energy and endurance during lovemaking, reducing common sexual problems such as erectile dysfunction (ED) or premature ejaculation. Positive reviews from Amazon.com and GNC have made it one of the most popular male enhancement supplements available today.

What ingredients are in Cobra?

Does Cobra actually work?

Yes - and it's effective. PDRHealth.com, a leading resource for physicians in the United States, lists muira puama as an effective treatment for erectile dysfunction (ED) and low libido, improving erection quality with regular use. It also contains anxiogenic properties, which increases energy levels quickly without causing any significant side effects.
Korean ginseng was also identified as an effective aid for ED in a study conducted by Sao Paulo University's Urological Division in Sao Paulo, Brazil. Taking Korean ginseng before intercourse improved erection quality, increasing the length of intercourse.
Don't leave out yohimbe bark extract either - it also contains an alkaloid called yohimbine, which helps reduce ED and a condition called orgasmic dysfunction, or an inability to orgasm while being sexually stimulated.

Is Cobra safe?

Not entirely. Yohimbe bark may cause high blood pressure, insomnia or skin flushing, making it potentially unsafe for people with heart or blood pressure conditions. It also increases a person's risk for panic attacks. There are few side effects associated with the rest of Cobra's ingredients.

Final Grade: D

Although it isn't as effective as Zyrexin, its ingredients are proven to attack ED at its core, making it easier to maintain an erection without additional physical stimulation. If you're looking for a great alternative to Zyrexin or Actra-RX, consider giving Cobra a try.
